Have you ever wanted to modify a .stl file that you’ve downloaded from a website like Pinshape or Thingiverse? While .stl’s are tricky to work with (similar to a really low resolution image), there is free software out there that will let you both modify and repair files to your hearts content!
My first tutorial as a guest writer for Pinshape has just been published, showing you how to modify a .stl file in 10 easy steps – just click the link to check it out. It’s very exciting to be writing for them, and I hope it helps give you the confidence to start customising your 3D prints, as this is really one of the great advantages of 3D printing in the first place.
You can also look back to some of my own past tutorials that I’ve created whilst working on particular projects, including using MeshLab to add text to a .stl, or turning a 3D form into a low-poly model. I must admit that I’ve now discovered Meshmixer (as featured in the Pinshape tutorial), and think it is a far easier tool to use than MeshLab. Both are free so check them out and see what suits you.
